Specification of Letters Patent. P

Application filed June 8, 1914. Serial l lo, 843,717.

To all whom it may concern:

Be it known that I, RALPH C. Boozer, a citizen of the United States,residing at Chicago, in the county of Cool; and State of Illinois, haveinvented certain new, and useful Improvements in Insulator-Supports, ofwhich the following is a specification.

This invention relates to improvements in insulator supports.

The invention is adapted more particularly for use in connection withmolded insulators made of glass, porcelain or the like having a taperedthreaded opening for mounting. It is practically impossible inmanufacturing molded insulators of this type to secure exact uniformityin the threaded bores due to the irregular shrink age of the materialduring cooling.

One of the objects of my invention is to provide a support forinsulators of this character which will adapt itself to irregularitiesin the tapered threaded bore without subjecting the insulator tounnecessary strain.

Another object of my invention is to provide a support of rugged, simpleand inexpensive construction adapted to be secured to a channel bar by asingle connecting member.

Other and further objects of my invention will be apparent to thoseskilled in the art from a consideration of the following de' scriptionand drawings, wherein:

Figure 1 is a vertical, central, sectional View through an insulator andsupport. Fig. 2 is a vertical central, sectional view through aninsulator and support, taken on a plane at right angles to that uponwhich Fig. l is taken. Fig. 3 is a top elevation of my improvedinsulator support, and Fig. 4: is a transverse, sectional view on theline of Fig. 1, with the insulator detached.

Referring to the drawings the numeral 10 indicates the body part of aglass insulator of a well known type having at its lower end theoutwardly flanged petticoat l1 and an axial tapering threaded bore 12.

The supporting bar 13 is of the usual channel shape, as is customarilyemployed threads of the insulator bore 12 is so mounted upon the supportas to provide dametric slot 18 separating the two halves let and 15.

As the insulator supporting shell i vanized to prevent iii-sting of the111. have cut away a circular dpening 17 upper end of the shell topermit of cleu the interior of the shell after the galvani' in process.This permits the flakes such as ma l be formed within the shell during tv vanizing process to readilv'slianu through the end. V w

The lower end of the semilinurical shell member Il-l below the is formedinwardly resulting in an arch like ortion 18-, the extreme lower endfitting a ainst the side of the bar 13 and having itsedg es formed overinto lips 19 which final-res old e contact with the outer sides of thechannel bar 18. The other shell member 15 its lower end is 1 at the openside of the channel bar and at its lower end carries a tab lient rightangles to the axis of the cvlindrioal. shell making a tight fit withinthe channel of the bar 13. A rivet 23 takes through the welo of thechannel bar and the lower ends 18 and 2O o f the semi-oylindrical shellmembers.

The lips l9-2l together with the tab 22 and rivet :23 rigidly connectthe semi-cylindrical shell members Liand 15 with the no per end of thechannel bar 13 providingn sturdy, eliioient connection andat the sametime permitting the upoer free ends of the semi-cylindrical shell 1.nhers to move radially inwardly or outwardly in order to adaptthemselves to variations in the threaded bore of the insulator.

lVhereas I have illustrated and described a single embodiment of myinvention, it is obvious that various changes may he made intheconstruction without departing from the spirit and scope thereof,

Having described my invention, what I claim 1s:-

1. An insulator support, comprising a si1 )porting channel shaped. post,two iridependent semi-cylindrical threaded sections, the lower ends ofthe said sections being formed inwardly to contact with opposite sidesof the channel post, lips formed. on the edges of the inwardly extendingends of the said sections, and means for rigidly connecting the lowerends of said sections in spaced relation to an end of the supportingpost, the upper ends of the said sections lee-- ing spaced away fromeach other, substantially as and for the purpose setforth.

2. An lnsulator support, COIDPIlSlIlg a formed inwardly to contact withopposite sides of the channel post, lips formed on the edges of theinwardly extending ends of the said sections, atah formed on the lowerend one of the said sections and extending into the channel of the saidpost and means for rigidly connecting the lower ends of said sections inspaced relation to an end of the supporting post, the upper ends of thesaid sections being spaced away from each other, substantially as andfor the purpose set forth.

3. An insulator support, comprising a supporting channel shaped post,two indewardly extending ends of the said sections,

a tab formed on the lpwerend of one of the said sections and extendinginto the channel of the said post and means for rigidly connectingthelowerends of said sections in spaced relation to an end of thesupporting post, the upper ends of the said sections being spaced awayfrom each other, substantially, asand for the purpose set forth. 4 v

In testimony whereof I hereunto set my hand in the presence of twosubscribing witnesses.
